In early iterations of the lobby map generation logic, a for loop was
used to retry map generation with alternative seeds in case it
failed. This seed randomization logic didn't exist in the final merged
version, but the for loop wasn't cleanup up, and ends up repeating any
map generation failures 5 times deterministically.
Additionally, the logic caught Exception instead of the more specific
MapGenerationException, which is the only exception that is expected
to arise in healthy builds/configurations (due to bad luck rather than
bugs).
This change:
- removes the for loop;
- only catches MapGenerationException;
- adjusts the user-visible failure message to reflect that trying
again (without adjusting settings) is a valid course of action (now
that it's not done internally);
Generated maps are created at runtime using a
mod-defined trait. They are embedded directly
into replays and save games as they exist in
memory only, and disappear after the game exits.
Exposes the TilingPath code used by the map generator as a map editor
tool to help automate the process of tiling sequences of templates
together.
No additional template stitching definitions are added as part of this
commit. As such, the tool currently only supports the same auto tiling
as the map generator does. This includes:
- RA and CnC support.
- Beaches, land cliffs, and roads.
Support for additional mods and templates can be added in follow-ups
by adding the necessary MultiBrush definitions.
Related changes included in this commit to support this work include:
- Add support for sparse EditorBlits.
- Add support for MultiBrush to EditorBlitSource conversion.
- Add support for EditorBlitSource previewing.
- Adjust the "Road" types used in segmented MultiBrush definitions.
Add an experimental procedural map generator for the Red Alert mod,
along with supporting code that may assist in the development of map
generators for other mods.
Map generation may be accessed as a tool in the Map Editor. This change
does not presently introduce direct lobby options for generated maps.
Features:
- Terrain with land, water, beaches, cliffs, roads, debris, and trees.
- Placement of mpspawns, neutral buildings, and resources.
- Rotational and mirror symmetry options.
- Various configurable parameters with presets.
- Deterministic with configurable seed.
- Performant.
